Amplifiers — Manufactured by STMicroelectronics

The LM124/LM224/LM324 series consists of four independent, high-gain, internally frequency-compensated operational amplifiers. These devices are designed to operate from a single power supply over a wide range of voltages, though they also support split-supply configurations. Their primary advantage is low power consumption combined with a wide common-mode input range that includes ground. This makes them highly versatile for general-purpose signal conditioning and amplification tasks in battery-powered or space-constrained applications.
